I've recently purchased the walking dead on steam. I have played through episodes 1-4. When I got to start episode 5 the game proceeds to the next screen and gets stuck on a black screen permanently. My only options then are force quitting the game. I've tried starting a fresh game on episode 5 alone only to have the same thing happen.
Im running the latest version of OS X 10.8.4.
I've run the support code and attached one of the files. The data file is too large for the forum's size restrictions.
